Welcome to Masterful: The Training Platform for Computer Vision Models


Masterful is the training platform for computer vision models.

Masterful is designed with three objectives:

  1. Accuracy, achieved via comprehensive regularization and semi-supervised learning (e.g. learning from raw, unlabeled images).

  2. Developer Productivity, achieved via high-speed metalearning. It’s a waste of developer time to guess-and-check of hyperparameters or do long runs with a black box optimizer.

  3. Speed, or minimizing GPU-hours and wall clock time, achieved via high-speed metalearning to discover ideal optimization hyperparameters.


Users define the two inputs to Masterful:

  • Data

  • Model architecture

Masterful processes these inputs through four modules:

  • Regularization, which improves accuracy from the existing information.

  • Semi-supervised learning (SSL), which improves accuracy by learning from the information in raw, unlabeled images.

  • Optimization, which minimizes GPU-hours and wall-clock time of training.

  • Meta-learning, which minimizes developer “guessing and checking” and eliminates black box optimization.

Masterful returns a trained model (e.g. model weights).

Masterful supports most types of classification, detection, and segmentation.

Currently available for Tensorflow2, with PyTorch support coming soon.

Getting Started

Install with pip install --upgrade pip; pip install masterful.

For detailed installation instructions, visit the Installation Tutorial.

Then execute your first training run with Masterful with the Quickstart Tutorial.

Finally, visualize Masterful’s performance with the Frontend Tutorial.
